Patented Fei). 13, 1951 f :TEN T FF l CE) by direct and mesne assignments, to Ace Storm WindowCompany, Youngstown, Ohio, a corporation ofy Ohio ApplicationAuguslth, 1945, Serial,No. 609,45 5p invention relates. to. a Stormi SashY and' more particularly to a frame and sash combina,- tion. fr

TheVv principal Object of thefillventon is the provision` of as stormsash comprising a Suitable frame and.. doulole` hung. SashV Combination- Ay further o bjectof the invention is the provision of a stormsashnipor a window opening in a dwellingA or other building, and'l incorporating an assembly ofv interlocking material shapes for the formation of the sash and the sash carrying frame.

A s till further object ofA the invention is the provision oia storm sash incorporati'ng a chann eledj frame and a plurality of` modiiication pieces engagable with the saidv channeled frame for forming a completedframe andjslidable sashc ombination` y stillfurther object othe invention is the provision-ofa storlmfsash for a window opening incorporating means for alixing the-sash to an inner portion ofv thel said window` opening.

The storm s ash shownand described' herein hasbeen designedto form an efficient insulating window for ak conventional window opening and is adapted to be assembled from a plurality of meta-lshapesso` as to for-man eioientl storm sa-sh frame and' framed sash slidably positioned therein.- lThe principal pointl ofi: novelty in the disclosure is the formationof` thestorm sash frame assemblyand the slidablesash. assemblies from a plurality'ofmetallic shapes preferably of extrudedA aluminum orv similar material. The frame andl sash` combinationy Ain completed form possesses several advantages over storm sash heretoforeknown inA the art, bothas to the'. ease of assembly and the efficiency ofA the-completed storm sash construction With-the foregoing and otherobjects in view which will appearl as the` description proceeds, the invention residesin the-combination and arrangement. of. partsv and' in theI detailsv of construction-l hereinatterf described. and claimed, it being understoodthatV changes in the. precise embodimentf'ofithe vinvention-herein disclosed 'can be made-.Withinthe scope of-*What lis=clain^led1without departingA from thespirit ofxtheinvention.

By referring to the drawings and- Figurev 1 and 2 in particular, it will-be seen thatastorm sash has` been disclosed which consists of a rectangu-v lar frame formed of; four appropriatelycut and. mitered sections of channeled framing material, it), the said1 framing 1naterialit including a sur-1 face flange l'l and an upstandingcentrallyfdis-l posed axially extending rib I2- which in turnv is; provided along. either side thereof with a paireof; oppositely disposed dovetaied channels IS- such. as shown in my co-pending patent application, Serial No. 608,199` led August 1, 1945 and now abandoned;

In order thata frame formed of sections of the framing material It may be used'forrsatisfactorily mounting a pair of sash in double hung relation therein, a plurality of secondary framing members are incorporatedy into theV said frame and consist oifa top sash guide I4 havinga pair ofdownwardly extending flanges MA and MB, a bottom sash guide l5 having, an upwardly and outwardly extendingange l5A,'a pair of lower sash side guides i6 (see Figure 3), each of which has an inwardly and outwardly formed fiange IGA and a back flange IBB, and aA pair of upper sash side guides Il (seeFigure 4), each of which has an inwardly` turned iiange HA forming a flat innermost surface; Each of the sash guides I4, I5', I8 and Ill areV also provided with dovetailed extensions HSC, I5C, IBC, and VFS, respectively, al1 of which dovetailed extensions register with the inwardly facing dovetailed channel i3 in the rib |2- of the framing member I0= from which the rectangular frame ofv the storm-sash is' formed. 1t will thus'be seen that-by adding these several appropriately cut sections to the essential frame formed of the framing members I0, a uniquely shaped storm sash frame is formed which can receive and retain in removable relation a pair of sash, such as illustrated inFigures 1, 2, 3, and e of the drawings. The upper sash consists of a section of gfass I8 having a frame l9'oi H-shape in cross section positionedon the four sides thereof. The double channels formed by theY H-shaped frame I9 are indicated by the numerals 20. and 2|, respectively, and it will be observed that the outermost channel Znns engagedmpon .the depending flange 3 MB of the top sash guide I4 while the bottom portion thereof rests upon the outermost ends of the flanges IGA of the lower sash guides I6 which terminate immediately thereunder.

By referring to Figure 4 of the drawings, it will be seen that the edges of the upper glass frame I9 rest against the flat surfaces of the flanges I'IA of the upper sash guides Il. Contact is also made between the front edge of the sash frame I9 and the framing material I I to provide a weathertight closure at this point. It will thus be seen that the uppermost sash consisting of the glass panel l'and frame I9 can be removably positioned within the upper outward half of the storm sash frame and is so formed that a weather-tight closure is effected between the same and the frame. The lower sash consists of a glass panel 22 framed about by an H-shaped frame 23 exactly the same as the frame I9 heretofore referred to in connection with the upper glass panel I8, and the outwardly and inwardly facing channels of the lower sash frame 23 are indicated by the numerals 2liand 25, respectively.

By referring now to Figure 3 of the drawings it will be seen that the portion of the glass frame 23 overlying the outwardly facing channel 24 lies within the channel formed by the ange ISB on the lower sash guide I5. This construction permits the lower sash carrying the glass panel 22 to slide vertically between the lower sash guides I6 and thereby form a weather-tight closure with respect thereto and the framing members I upon which the sash guides IS are carried. It will be observed by referring to Figure 2 that the sash guides I6 terminate beneath the bottom-most portion of the upper sash frame Iii and it will therefore be obvious that the lower sash frame 23 may be removed from the window by simply raising it to position above the ends of the anges IBB of the lower sash guides I6 and lifted from the storm sash structure. When this has been done, the upper sash frame I9 may then be removed by swinging the lower end of the frame thereof inwardly which will permit it to move off of the upper end of the lower sash guides It and permit it to be lowered suiiicienty to disengage the channel Zi) in the frame I from the downwardly depending ange MB. For summer-time storage the normally lower sash frame 23 may be simply moved vertically and its uppermost end registers with the downwardly depend'ng flange IBA of the sash guides I4 and a' screen insert of comparable size and framed in the same manner as the glass panel 22 may be positioned ther inunder on the guides it and held thereby.

' It will thus be seen that a simple and ecient storm sash construction has been disclosed which may be simpy and efciently constructed from a plurality of cut sections of strip material such as extrusions and that in assembled relation the several component parts form a storm sash assembly possessing the unique advantages of easy assembly,` simple construction and weather-tight characteristics. lt will be obvious to those skilled in the art that some method of joining the sections of the framing material lil to one another must be provided to form an integral frame and several alternate methods are available, as shown' in my co-pending patent applications, Serial No. 608,198 led August l, 1945, now Patent No. 2,447,- 347, and Serial No. 608,197 filed August l, 1945, now Patent No. 2,447,346.

In the present disclosure L-shaped corner pieces 26 are employed and it will be observed that they register with the outermost channels I3 formed on the upstanding ribs I2 of the framing material I0. The same construction is employed in uniting the glass frames I9 and 23, L- shaped corner pieces 21 being utilized, the same lying in the outermost channels 2t and 24 of the frames I9 and 23, respectively. In both of these corner constructions a press fit between the respective channels and corner pieces is deemed sufficient to form a satisfactory frame assembly. However, it is obvious that various fastening means as known in the art and especially to those skilled in the art, may be employed in addition to the press t characteristics to effect a desirable frame construction between the cut framing pieces and the corner pieces, respectively.

It will thus be seen that an efficient storm sash has been disclosed which may be readily formed on the job if desired, in any size, from simple extruded lengths of material cut to size, mitered and assembled without the necessity of complicated fastening tools or forming jigs or fixtures.

Having thus described my invention, what I claim is:

l. A storm window comprising a rectangular shaped frame including side members each having spaced longitudinally extending opposed inwardly directed front and rear flanges forming a dovetailed channel therebetween, a pair of elongated modifying members positioned in said channels in oppositely disposed relation at the sides of and in the lower part of said frame, said modifying members each including a pair of longitudinally extending spaced oppositely disposed front and rear channel forming flanges in the rear part of said frame, and each of said modifying members having a part extending from the side marginal portion of its front channel forming flange fitting against one of the front flanges of the frame and constituting with said front channel forming flange a filler block portion, a secondary pair of elongated modifying members positioned in said channels in oppositely disposed relation at the sides of and in the upper part of said frame, each of said secondary modifying members having a part extending between the front flange of the frame and the rear flange thereof and at a right angle thereto, a pair of sash, one located in the said channels of the modifying members in the lower rear portion of the frame and the other positioned on the upper ends of the said filler block portions in the front portion of the frame with its side edges in registry with said secondary modifying members.
